Nope.

what is it that prompts the question?

Is it leaking? you can tighten the gland nut to resolve that.

It is FULLY tightened and metal to metal, it is slightly better but still dripping.

Nope.

So the system would have to be drained !!!

Lol make sure u got towels handy if u undo that with system full.
Yes it needs to be drained and change lock shield valve

yes

I don't drain them, just shut lockshield, undo packing gland nut, re-pack with jet blue & loctite cord & re-open... shouldn't see any water at all

Find it strange if answers above are from Plumbers ???

Cheers anyway

Good afternoon. You asked if you could remove the part you use to turn the rad on/off not the gland and you also did not mention that it was weeping. The people on here are just trying to help. Please try to be more specific in the future.

Sorry i did google to try and find the name of the part, the best i could find was the pic i posted....I guess if i had added the part arrowed that is inside the lockshield, people would of been aware.

So it's a GLAND, thanks for all your replies and sorry if i offended anyone, it was not intentional...

Can anyone explain how the water does not 'squirt' out though, what else is there to stop it?

Thanks Guys

The gland nut holds down the packing around the valve spindle which stops water seeping through the tiny gap between the spindle and the valve body. If you close both rad valves and open the air vent on the rad to release any remaining pressure you will get hardly any seepage. Undo the nut and put in new packing (PTFE tape will do for a temp fix) replace nut, open valves and tighten nut enough to stop any weeping. Open and close the valve a couple times to make sure.
